What of the gasses is N and the flame changes it's color from Orange to blue
Answer:
the Bohr model, an electron's position is known precisely because it orbits the nucleus in a fixed path. In the electron cloud model, the electron's position cannot be known precisely. Only its probable location can be known.
Deforestation- there are no more homes for some animals and insects after a forest is cut down.
desertification- when deserts get larger it destroys other ecosystems.
7 valance electrons and a atomic number of 9
<u>Answer:</u> The molecular weight of protein is
<u>Explanation:</u>
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
or,
where,
= Osmotic pressure of the solution = 0.0861 atm
i = Van't hoff factor = 1 (for non-electrolytes)
= mass of protein = 400 mg = 0.4 g (Conversion factor: 1 g = 1000 mg)
= molar mass of protein = ?
= Volume of solution = 5.00 mL
R = Gas constant =
T = temperature of the solution =
Putting values in above equation, we get:
Hence, the molecular weight of protein is
